Abstract

The invention provides a tooth surface parameter acquisition method based on three-dimensional modeling of a spiral bevel gear milling tooth surface and relates to the field of information technology.The method comprises the steps that according to a bevel gear and bevel gear milling technological parameters, a gear blank three-dimensional model and a milling cutter tooth blade track surface three-dimensional model are established, and a single milling cutter tooth blade processing three-dimensional model is established; Boolean operation is performed on the gear blank three-dimensional modelthrough the milling cutter tooth blade processing three-dimensional model to obtain a single-arc-tooth profile three-dimensional model, and the single-arc-tooth profile three-dimensional model is adopted to construct single-arc-tooth profiles repeatedly on the gear blank three-dimensional model to obtain a milling spiral bevel gear three-dimensional model; and based on the single-arc-tooth profile three-dimensional model, tooth surface roughness of the milling spiral bevel gear three-dimensional model is acquired. The simulation can accurately reflect the influences of feeding quantities, milling cutter parameters, gear parameters and other factors on the surface roughness of the spiral bevel gear tooth surface.

Problems solved by technology

Among them, the experimental method is to use the surface roughness meter to measure the surface roughness of milling gear processing, and the three-coordinate measurement method is to measure the three-dimensional coordinates of the milling gear processing surface to construct a three-dimensional model of the processing surface. The experimental cost of the two methods is high, and it is difficult to reflect the surface roughness. The direct relationship between roughness and feed rate, milling cutter parameters, gear parameters and other main influencing factors cannot obtain the three-dimensional shape of the tooth surface
